Get a Stamen Map

get_stamenmap() accesses a tile server for Stamen Maps and downloads/stitches map tiles/formats a map image. Note that Stamen maps don't cover the entire world.

get_stamenmap(
  bbox = c(left = -95.80204, bottom = 29.38048, right = -94.92313, top = 30.14344),
  zoom = 10,
  maptype = c("terrain", "terrain-background", "terrain-labels", "terrain-lines",
    "toner", "toner-2010", "toner-2011", "toner-background", "toner-hybrid",
    "toner-labels", "toner-lines", "toner-lite", "watercolor"),
  crop = TRUE,
  messaging = FALSE,
  urlonly = FALSE,
  color = c("color", "bw"),
  force = FALSE,
  where = tempdir(),
  https = FALSE,
  ...
